Description

Detailed Description of the Invention

[0001]

[Industrial field of use] With the spread of telephones, telephone systems are becoming widespread in offices of companies, etc., in which a telephone number is assigned to each individual and a person with whom communication is desired can be called directly. On the other hand, the multi-zone cordless phone system for offices allows you to make and receive phone calls wherever you are in the office, providing a new form of phone usage where individuals carry their cordless phones and move around. To do. The present invention relates to a telephone calling system in the case of combining both of them, and in particular, the same telephone number is given to a desk telephone (wired telephone) and a cordless telephone, and a physical positional relationship between the two is managed by an exchange. However, the present invention relates to a telephone calling system that calls a predetermined telephone when an incoming call arrives at the number based on the positional relationship.

2. Description of the Related Art FIG. 14 is a block diagram of a cordless telephone system having a multi-zone structure which has been conventionally provided.
Is a PBX (Private Branch Exchange), 2 ₁ , 2 ₂ and 2 ₃ are cordless connection devices, 3 ₂ and 3 ₃ are cordless telephones, and a number of desk telephones (wired telephones) are also provided although not shown. The cordless connection devices 2 _{1 to} 2 ₃ send and receive signals to and from a cordless telephone by transmitting radio waves of signals and voice signals for making and receiving telephone calls, and have a limited reach of radio waves. Therefore, the cordless connecting device is installed on each floor 1F~3F for example building BL, and configured to cover the entire building (entire telephone service area) by a plurality of cordless connecting device 2 ₁ to 2 _3. The range within which radio waves from one cordless connection device can reach is called a zone. A cordless telephone system with a multi-zone configuration is thus composed of multiple zones # 1 to # 3, and which zone the cordless telephone moves to. Can also make and receive phone calls and make phone calls.

For example, in FIG. 14, the cordless telephone 3 ₂ on the second floor talks via the cordless connection device 2 ₂ on the second floor, but when it moves to the third floor, it goes through the cordless connection device 2 ₃ on the third floor. Make a call. In addition, in the cordless telephone system having the multi-zone configuration, the PBX 1 manages the zone in which each cordless telephone exists by performing a process of location registration so that the incoming call to the cordless telephone can be performed smoothly. That is, PBX1
Holds a correspondence table (phone number-registered zone correspondence table) TLZ between the telephone number and the zone in which the cordless telephone having the telephone number exists in the memory 1a.
When an incoming call arrives at No. 001 cordless telephone 3 ₃ , PB
X1 sends out an incoming signal only to the cordless connection device 2 ₃ on the 3rd floor, and the 2001 cordless telephone 3 ₃ on the 3rd floor
The incoming calls are made smoothly.

In such a conventional cordless telephone system having a multi-zone structure, the telephone number of the cordless telephone is different from the telephone number of the telephone (wired telephone) installed on the desk. For this reason, the owner of the cordless telephone should disclose the telephone number of the cordless telephone in addition to the telephone on the desk (tell me), and ask the caller to call back the telephone number of the cordless telephone when he is not at his desk. , The call forwarding from the desk phone to the cordless telephone is registered so that the call can be received by the cordless telephone when moving by the call forwarding.

FIGS. 15 (a) and 15 (b) show a conventional telephone call.
It is explanatory drawing, and attaches | subjects the same code | symbol to the same part as FIG.

FIG. 15 (b) shows a case where Mr. A carries a 2000 cordless telephone 3 ₁ and moves to the second floor. Mr. A registers so that when he leaves his seat, the call received from 3000 is automatically transferred to 2000. By doing so, the telephone addressed to itself is automatically transferred to the 2000 cordless telephone 3 ₁ to receive the call. However, if you do not register automatic transfer,
I cannot receive an incoming call to the cordless telephone 3 ₁ . In such a case, if the caller is informed of the number of the cordless telephone, the caller can call the telephone number of the cordless telephone and call the telephone. In the case of FIG. 15 (b), Mr. A has 200
When the number 0 cordless telephone 3 ₁ is called to the number 2001, the number 2000 is displayed on the display portion of the number 2001 telephone 3 ₃ . In this case, if Mr. A discloses only 3000 personal telephone numbers, the owner of the 2001 telephone 3 ₃ cannot recognize that it is Mr. A's telephone.

[0007]

As described above, conventionally, the telephone number of the cordless telephone and the telephone number of the telephone (wired telephone) installed on the desk are different numbers. Therefore, the possession of the cordless telephone In addition to the desk phone, the person also discloses the number of the cordless phone, and when the person is not at his / her desk, asks the caller to call the phone number of the cordless phone again, or perform call forwarding from the desk phone to the cordless phone. By registering, you can receive an incoming call at a cordless telephone when you move by a call forwarding. However, in the former case, there is an inconvenience that the caller has to be aware of two numbers. In the latter case, it is sufficient to tell the caller only the telephone number of the desk phone, but there is a problem that registration work for call forwarding is necessary or the telephone number of the cordless telephone is visible to the other party and causes a problem. is there. For example, PBX has a service that displays the telephone number of the calling party on the display of the receiving terminal, but when a call is made from a cordless telephone, the number of the cordless telephone is displayed on the receiving terminal and the called party There is a problem that I can't tell if it is my phone.

In view of the above, the object of the present invention is to provide a telephone calling system in which the telephone number of a cordless telephone and the telephone number of a telephone set on a desk are made the same so that the caller does not need to be aware of the two numbers. It is to be. Another object of the present invention is to make the telephone number of a cordless telephone and the telephone number of a telephone installed on a desk the same,
It is an object of the present invention to provide a telephone calling system in which a called party can easily recognize from whom a call is made from a cordless telephone. It is still another object of the present invention to provide a telephone calling system capable of automatically receiving an incoming call to a cordless telephone without carrying out call forwarding registration when the user moves while carrying the cordless telephone.

Reference numeral 0i denotes a dedicated telephone, which detects the physical positional relationship between the wired telephone 14i and the cordless telephone and the wired telephone, and detects the PB.
It has a detection unit 15i for notifying X11. Since the cordless telephone 13i operates on a battery, it is usually placed on a charging stand when not in use. Dedicated telephone 40 of FIG.
i has a shape in which the charging base of the cordless telephone 13i is integrated, detects whether or not the cordless telephone 13i is placed on the charging base, and outputs the detection signal to the dedicated telephone (wired telephone) and the cordless telephone. It is used as information indicating the physical positional relationship of. In the figure, the wire telephone 14i
In the figure, 41 is a wired telephone circuit, and 42 is a handset. Further, in the detector 15i, 43 is a charging circuit for charging the battery of the cordless telephone mounted on the charging stand, 44 is whether or not the charging terminal of the cordless telephone is inserted, in other words, the cordless telephone is charged. A charging terminal contact detection circuit for detecting whether or not it is placed on a stand, 45 is a position information sending circuit, and based on the detection signal output from the charging terminal contact detection circuit 44, the positions of the cordless telephone 13i and the wired telephone 14i. The PBX 11 is notified of the related information (“near”, “away”). Hereinafter, the positional relationship registration processing between the cordless telephone and the wired telephone, the position registration processing for the cordless telephone, and the incoming call processing will be described.

Positional relationship between cordless telephone and wired telephone
Registration Process FIG. 6 is a flowchart of the positional relationship registration process of the telephone. The detection unit 15i of each dedicated telephone 40i (see FIG. 5) always discriminates whether or not the cordless telephone 13i is placed on the charging stand (step 101). The non-placed state → the placed state or the placed state. When the state is changed to the non-placed state, the positional relationship information (“close” or “away”) is notified to the PBX 11 (step 102). The PBX 11 is notified of the “near” data when the non-placed state → the mounted state, and the “separated” data when the mounted state → the non-mounted state. If the PBX 11 receives the positional relationship information from the dedicated telephone (step 10)
3), the positional relationship information stored in association with the telephone number of the dedicated telephone is changed to "distance" → "near" or "near" →
It is updated to "distance" (step 104). As described above, the PBX 11 always identifies and manages whether or not each cordless telephone 13i exists near the wired telephone 14i on the desk, in other words, whether or not the owner carries the cordless telephone and leaves his / her desk. be able to.

Location Registration Processing to which Cordless Telephone belongs Figure 7 shows PBX 11 in the zone where the cordless telephone exists.
5 is a flowchart of a location registration process for registering with the. In the cordless telephone system having the multi-zone configuration, the cordless telephone cannot be called smoothly unless the PBX recognizes the zone to which each cordless telephone belongs. Therefore, each cordless connection device 12i periodically puts the zone number (zone identifier) on the radio wave to notify when no call is being made (steps 201 to 202). When each cordless telephone 13i receives the zone number from the cordless connection device corresponding to the zone in which it is located (step 20).
3) Then, it is determined whether the zone number stored in the memory unit 23 (see FIG. 4) and the received zone number match (step 204). If they match, the process returns to step 201 and the subsequent processes are repeated.

On the other hand, if the received zone number is different from the stored zone number, it means that the cordless telephone 13i has moved to a different zone than before, and the memory unit 23
Is updated with the received zone number (step 20).
5). As a result, the cordless telephone 13i always holds in the memory section 23 which zone it is in. Then, the cordless telephone 13i transmits a position registration signal including its own telephone number and the latest zone number to the cordless connection device by radio (step 20).
6). When the cordless connection device receives the position registration signal from the cordless telephone, it notifies the signal to the PBX 11 (step 207), and the PBX 11 updates the telephone number / position correspondence table TLP based on the notified position registration signal ( Step 208) and thereafter waits for the next notification. That is,
The contents of the zone field corresponding to the notified telephone number are updated with the notified zone number (step 208).

For example, when the cordless telephone 13 ₁ is in zone # 2 (see FIG. 8 (a)), the cordless telephone 1
3 ₁ receives the zone number # ₂ from the cordless connection device 12 ₂ and stores it in the memory unit. In this state, when the cordless telephone 13 ₁ moves to the third floor (FIG. 8B), the cordless telephone receives the zone number # 3 from the cordless connection device 12 ₃ . Since the zone number stored in the memory is # 2, there is a discrepancy between the two. In this case, the cordless telephone 13 ₁ determines that it has moved between zones, updates the memory contents, and transmits a position registration signal (including the telephone number 3000 and zone number # 3).
When the cordless connecting device 12 ₃ receives the location registration signal, informs the PBX 11, PBX 11 rewrites the telephone number and position correspondence table TLP "cordless telephone 3000 Are Zone # 3" writes information that the memory 11c (FIG. 8 (c)). With such a mechanism, the zone can be managed.

Incoming Call Processing FIG. 9 is a flow chart of the incoming call processing. When a predetermined telephone number is called, the PBX 11 refers to the telephone number / position correspondence table TLP and checks the positional relationship between the cordless telephone and the wire telephone of the telephone number (step 301). If the cordless telephone is placed on the charging stand and is "near", the PBX calls the wired telephone 14i having the telephone number (step 302). On the other hand, if the cordless telephone is removed from the charging stand and is "away", the PBX obtains the zone number where the cordless telephone exists from the telephone number / position correspondence table TLP. Then, the cordless telephone 13i having the telephone number is called via the cordless connection device of the zone number (step 303). Then, the calling telephone number is notified to the called telephone and displayed on the display unit (step 304). In this case, even if the caller makes a call from his or her desk using a cordless telephone, since the personal telephone number of the caller is displayed on the display unit of the receiving telephone, the called party sees the number. You can only recognize who called you.

FIG. 10 is an explanatory diagram of the incoming call processing. PBX
11 stores and manages the positional relationship between the dedicated telephone (wired telephone) and the cordless telephone sent from the dedicated telephone 40i in the telephone number / position correspondence table TLP and manages the zone where the cordless telephone is located by telephone number / position. Store and manage in table TLP. FIG. 10A shows the case where Mr. A places the cordless telephone 13 ₁ on the charging stand of the dedicated telephone 40 ₁ . In such a case, when a call is made to Mr. A's personal telephone number 3000 from the cordless telephone 13 ₃ , the PBX 11 searches the telephone number / position correspondence table TLP, and the wired telephone 14 ₁ having the telephone number 3000 and the cordless telephone 13 _Find the positional relationship of ₁ . Since the positional relationship is "near", an incoming call is made to the wire telephone 14 _{1 and} the telephone number 7000 of the cordless telephone 13 ₃ is displayed on the display portion.

FIG. 10B shows the case where Mr. A is carrying a cordless telephone and is away from his seat. In such a case, if there is an incoming call to Mr. A's personal telephone number 3000, PBX11
Searches for the telephone number / location correspondence table TLP and
The positional relationship between the 00th wired telephone 14 ₁ and the cordless telephone 13 ₁ is obtained. Since the positional relationship is "distance", the zone number in which the cordless telephone 13 ₁ exists next is obtained. Since the zone number is # 2, the PBX 11 has the zone number #
A call is made to the cordless connection device 12 _{2 of 2} and A
Calling his 3000th cordless phone,
The display unit displays the telephone number 7000 of the cordless telephone 13 ₃ . As described above, it is possible to receive an incoming call with the cordless telephone while the user is away from the desk, without performing call forwarding registration. Even when a call is made from a cordless telephone, Mr. A's personal telephone number can be displayed as the caller number on the display section of the other party.

(B) Overall configuration of the second embodiment of the present invention FIG. 11 is another configuration diagram of the cordless telephone system of the present invention. The same parts as those of the first embodiment are designated by the same reference numerals. There is. The wired telephone 14i (i = 1,2,3) and the cordless telephone 13i (i = 1,2,3) have the same owner, and each has the same telephone number (3000,5000,7000). Has been granted. 11, the difference from the first embodiment of FIG. 2 is that there is no detection unit 15i (i = 1, 2, ...) For detecting the physical positional relationship between the cordless telephone and the wired telephone. Instead of the telephone number / position correspondence table TLP in the memory 11c of the PBX 11, the telephone number / zone correspondence table TLZN
Is the point to remember. This phone number / zone correspondence table TL
In ZN, the number of the zone in which the wired telephone having the telephone number is installed and the number of the zone in which the cordless telephone exists are stored in association with the telephone number. The registration process (location registration process) of the zone in which the cordless telephone is present is exactly the same as in the first embodiment (see FIG. 7). The incoming call processing of the second embodiment will be described below.

Incoming Call Processing FIG. 12 is a flowchart of the incoming call processing. When a predetermined telephone number is called, the PBX 11 displays the telephone number / zone correspondence table TL.
The zone numbers of the cordless telephone 13i and the wired telephone 14i of the telephone number are checked by referring to ZN, and it is judged whether both telephones are in the same zone (step 401). If the zone numbers are the same and both telephones are in the same zone, the PBX will be the wired telephone 14i with the telephone number.
Is called (step 402). On the other hand, if the two telephones are not in the same zone, the cordless telephone 13i having the telephone number is called via the cordless connection device having the zone number in which the cordless telephone exists (step 403). Then, the calling telephone number is notified to the destination telephone and displayed on the display unit (step 404). In this case, when the caller makes a call from his or her desk using a cordless telephone, the personal telephone number of the caller is displayed on the display part of the receiving telephone, and the called person sees the number to whom the call is made. You can recognize what was there.

FIG. 13 is an explanatory diagram of the incoming call processing. PBX
Numeral 11 monitors the zone in which the wired telephone is installed and the zone in which the cordless telephone exists, and the numbers (zone numbers # 1, # 2 and # 3) are telephone number / zone correspondence table TLZN.
Remember and manage. FIG. 13A shows the case where Mr. A is near his seat, and the zone number # 1 is registered in the correspondence table TLZN as the zone in which the cordless telephone 13 ₁ exists. In such a state, Mr. A's personal telephone number
If you call 3000 with cordless telephone 13 ₃ , PBX
Reference numeral 11 searches the telephone number / zone correspondence table TLZN to find the installation zone of the wired telephone 14 ₁ with the telephone number 3000 and the existing zone of the cordless telephone 13 ₁ . Since both the installation zone and the existing zone are the same in # 1, the incoming call is made to the wired telephone 14 _{1 and} the telephone number 7000 of the cordless telephone 13 ₃ is displayed on the display section. On the contrary, Mr. A uses the wired telephone 14 ₁ or the cordless telephone 1

(C) Other Modifications In the first embodiment, the positional relationship between the cordless telephone and the dedicated telephone is detected by the physical contact between the cordless telephone and the dedicated telephone. However, weak radio waves are transmitted and received between the cordless telephone and the dedicated telephone. As a result, the positional relationship between both telephones can be detected. Further, in the first embodiment, the physical relationship between the cordless telephone and the dedicated telephone is detected to notify the PBX of the positional relationship between the two telephones, but the positional relationship is not provided with the dedicated telephone but with the telephone with the function button. Can be configured to notify the PBX. For example, on the function button, "Attend / Leave"
This function is assigned to call a desk phone when "attended" is selected and a cordless phone when "away" is selected. In such a configuration, it is necessary to operate the function button of the desk phone when leaving the desk, but there is an advantage that the telephone call control of the present invention can be performed with a simple configuration using a conventional telephone. Although the present invention has been described above with reference to the embodiments, the present invention can be variously modified according to the gist of the present invention described in the claims, and the present invention does not exclude these.

[0028]

As described above, according to the present invention, when an individual owns a cordless telephone in addition to a desk telephone, only one telephone number is disclosed as an individual telephone number, and when the person is at the desk, the telephone number is displayed on the desk. You can receive incoming calls on your telephone, and you can receive incoming calls on your cordless telephone while you are away from your desk by carrying a cordless telephone. It is possible to eliminate the work of registering the call forwarding of, and greatly improve the convenience of the telephone. Further, according to the present invention, the same number (personal telephone number) can be displayed as the caller number on the display unit of the receiving side telephone depending on whether the telephone call is from a desk phone or a cordless telephone. Also in this case, the called party can recognize from whom the call is made.
